PIPE-CLAMR rename.

To all whom it may concern Be it known that l, fvil()R"IMER G. RUBEN"ELD, a citizen of the United States, residing at Cleveland, in thecounty of (Juyahoga and State of Ohio, have invented a certain new anduseful Improvement in Pipe- Ulamps, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings.

This invention relates to pipe clamping devices and more particularly todevices of this kind which are particularly adapted to be clamped toadjacent ends of pipe sections to afford a means whereby these sectionsmay be drawn together. Heretofore it has been proposed to accomplishthis result in connection with a pair of clamps, each clamp consistingof a plurality of clamping members and each member being adapted toembrace a segment of the rounded surface of a pipe, there being boltsfor coupling said clamping members together, the bolts extending throughhalf-eyes in adjacent 1nembers cooperating to form complete eyes for thereception of such bolts. By adjusting the bolts, the pipe ends areforced into operative relation to each other. This construction isliable to the objections that, in order to accommodate the bolts whichextend from clamp to clamp, it is necessary that each clamping member beof such angular extent and fit the pipe so exactly as to bring the endsof adjacent clamp segments in close proximity; otherwise, the projectingends of these members or segments will not abut and the eye formed inthe opposed clamping extensions will be distorted, frequently so much asto be incapable of retaining a bolt therewithin.

it is the object of this invention to provide an extremely simple andeconomical clamping device which will have a wide range of adaptability,the members of which will be interchangeable, and which may be adjustedto suit varying sizes of pipes without affecting the size and operativelocations of the eyes which receive the clamping bolts. 1 acomplishthese results by the construction illustrated in the drawings formingpart hereof, wherein- Figure 1 represents an elevation showing theabutting ends of two pipe sections with my clamping devices appliedthereto; Fig. 2 a sectional detail corresponding to the lineSpecification of Letters Patent.

2-2 of Fig. 1; and Fig. 3 a view, similar to Fig. 2, of a modified formof the invention.

Describing by reference characters the parts illustrated herein, 1 and 2denote the opposed and adjacent ends of a pair of pipe sections, thesection 2 being shown as provided with a hub 3 which the end of theother section enters. For the purpose of drawing these pipe sectionstogether and forming a tight joint, I apply to the adjacent ends of thesections a pair of clamps and draw these clamps, and the attached pipesections, together by means of bolts connecting the clamps. Each clampas shown in Figs. 1 and 2, comprises a pair of symmetrical andinterchangeable members constructed as follows: 4: denotes a curvedsegmental strap, the curvature being approximately that of the pipesection with which it will be employed and its angular extent beingapproximately 180, where each clamp comprises but two segmental members.This strap is provided with a lug 5 projecting from one end thereof andprovided with an aperture for the reception of a bolt. At its other endit is provided with a lug 6 which is also provided, adjacent to thecurved part of the strap, with an aperture for a bolt, but is providedwith an extension formed into an eye 7, said eye projectingsubstantially at right angles from the lug 6 and toward the adjacent andcooperating member of the clamp. Cooperating with the member justdescribed is a duplicate thereof having the lugs and eye described. lnassembling, the lug 5 of one of the clamping members is placed on thesame side of the pipe as the lug 6 of the other member and the clampingmembers are con nected by means of bolts 8 extending through theapertures in the said lugs. When the parts of the clamp are connected,the complete clamp will be provided with a pair of symmetrical, opposedeyes 7. Owing to the length of the lug 6, the eye 7 will clear the endof the lug 5 as the opposed clamping members are adjusted toward eachother. Furthermore, even though considerable space exists between thelugs of the opposed clamping members, as when they are applied to pipesof considerably greater size than they will exactly lit, the centers ofthe eyes 7 will be substantially half-way between the lugs 5 and 6,whereby these eyes will be in symmetrical relation to the pipe sectionsand to the clamp, enabling an eflicient conpllng to be made between thepipe sections when the coupling bolts are applied to the eyes of theclamps on the said section.

In connecting a pair of pipe sections, it is only necessary to apply theclamps to said sections in the manner shown in the drawing, taking carethat the eyes of one clamp are in alinement with those of the other. Thecoupling bolts 9 will thus be applied to these eyes and the pipesections be forced into close and leak-proof engagement by means of thenuts 10.

In Fig. 3, each clamp is shown as composed of more than two symmetricalmembers, four such members being illustrated. Each member, however, issubstantially identical with each member of Figs. 1 and 2, differingtherefrom only as to its angular extent, the segment in this case beingapproximately 90 instead of 180. In this construction the clamps can bedrawn together by four bolts spaced 90 apart instead of by two boltsspaced 180 apart. Among the advantages of this construction are theinterchangeability of the segmental members of each clamp the cheapnessof construction (made possible by the use of a complete eyein eachclamping member and by the interchangeability of the members); theconvenience of application to the pipe sections (secured by thearrangement of the eyes whereby adjustment of the clamping members ispermitted and ample clearance is provided between the connecting boltsand the hub); also the efficiency secured through the balanced orsymmetrical location of the eyes.

Having thus described my invention, what I claim is 1. A clamping devicefor the purpose set forth comprising a plurality of symmetrical clampingmembers each having a short clamping lug and a long clamping lug atopposite ends thereof, the long clamping lug being provided with an eyeand the clamping members being arranged so that the short lug of one isadjacent to the long lug of another, and means adjustably connecting thelugs of said clamping members, the connecting means being locatedbetween the eye of the long lug and the body of the member carrying thesame.

2. A clamping device for the purpose set forth comprising a plurality ofsymmetrical segmental clamping members each having a pair of clampinglugs projecting from opposite ends thereof, one of the lugs of eachmember being provided with an eye and the clamping members beingarranged so that the eye of one member is adjacent to an eye less lug ofthe other, and means adjustably connecting the lugs of said clampingmembers, the connecting means being located between the eye of the longlug and the body of the member carrying the same.

3. A clamping device compri ing a plurality of clamping members eachhaving at one end a short lug and at the opposite end a long lugprovided at its end with an eye, said clamping device being arranged sothat the short lug of one member is adjacent to the long lug of anotherand the eye on the long lug of each clamping member projects toward andadapted to overhang the short lug of the cooperating member, and meansadjustablyconnect-ing the lugs of said members.

4.1 clamping device comprising a plurality of clamping 7 members eachhaving lugs at opposite ends thereof, one of said lugs being providedwith an eye, said clamping device being arranged so that the eye on eachclamping member projects toward the eyeless lag of the cooperatingmember, and means adjustably connecting the lugs of cooperating members,the connecting means being located between the eye of the long lug andthe body of the member carrying the same.

A clamping device comprising a plurality of clamping members each havinga short lug atone end and a relatively long lug at the other end, thelong lng being provided with an eye at its end and the clamping membersbeing arranged so that the short lug of one member is adjacent the longlug of another member and the eye on each member projects toward, but islocated beyond the end of, the short lug of the cooperating member,whereby said mem bers may be adjusted toward and from each other, andmeans acljustably connecting the lugs of th members.

In testimony whereof, I hereunto aiiix my signature in the presence oftwo witnesses.
